The metal traditionally used for electrical wiring, due to its excellent conductivity, is copper. Copper is favored in electrical applications because it is a highly efficient conductor of electricity, which helps reduce energy loss during transmission. Its malleability allows it to be easily drawn into wires of varying thicknesses. Additionally, copper has good resistance to corrosion, which enhances its longevity in electrical installations. In some cases, aluminum is also used for electrical wiring, particularly in power lines, but copper remains the standard choice for home wiring and electronics. The effectiveness and reliability of copper make it an indispensable material in the electrical industry.
